To all whom it may concern:

Be it known that 1, JOHN H. GRISSINGER, a citizen of the United States,residing at WVellington, in the county of Lorain and State of Ohio, haveinvented a certain new and useful Improvement in Gas-Producers, of whichthe following is a full, clear, and exact description.

This invention relates to improvements in apparatus for producing afixed gas from crude oil.

The object is to provide a gas producer adapted for said purpose in suchform that it is of moderate first cost and can be economically operatedon a commercial scale.

The improvements as shown in the accompanying drawings are clearlydescribed herein, and the claims clearly define such improvements.

In the drawing, Figure 1 is a front elevation of a gas producerembodying the invention with a part of the front of the producer brokenaway, so as to show some of the retorts and one side of the furnacewalls in section; Fig. 2 is a longitudinal vertical section of saidproducer; Fig. 3 is a rear elevation partly broken away; and Fig. 4 is aplan view of the three stabilizers.

Within suitable furnace walls A, which may, for most part, be built ofbrick, are the fire box B, the retort chamber G, which is above the firebox; and the stabilizer chamber D, which is above the retort chamber.Within the fire box B is a burner F, or other means for supplying thenecessary heat. Within the retort chamber are a plurality of retorts E,which rest upon metal beams H. The sides of these retorts are sinuous,as shown; and the retorts are gradually widened from bottom to top. Whena plurality of these retorts are placed side by side within the retortchamber, as shown, there will be between them sinuous flues K, whichwill be gradually decreasing in width from bottom to top. It is throughthese flues that heat from the fire box flows upward in intimate contactwith the retorts and into the stabilizer chamber; and because of thesinuous form of the side walls of the retorts, these side walls havemore surface exposed to the action of the heat than would be the case ifthe walls were straight. The ends of these flues at both the front andrear of the furnace are closed gas which by sinuous strips G of asbestosor other suitable refractory material. Plates M of similar materialformed with sinuous inner faces are secured in the side walls of thefurnace adjacent to the two outside retorts, so that there will beformed between these outside retorts and said plates sinuous flues likethose between the retorts. The strips G which form the ends of theseveral fiues may be held in place by plates of asbestos or othersuitable material secured. in metal frames P at both the front and rearof the furnace. The upper walls of these frames are a considerabledistance above the top of the retorts and these asbestos boards M extendto this upper wall, so as to form a part of the front and rear walls ofthe stabilizer chamber. These frames are formed by outwardly projectingflanges on vertical plates secured to the front and rear furnace walls.

Each retort E is divided by horizontal partitions e which alternatelyextend from the front and rear walls nearly to the opposite walls. Thisforms a plurality of horizontal compartments which are connected inseries,the connections being around the ends of said horizontal partitions. A mixture of oil spray and air is delivered through the frontwall of each retort from an atomizer Q into the lower compartment ofsaid retort. Each retort at its rear end is enlarged downward so as toform at the rear end of the bottom compartment a settling chamber forthe reception of the non-violatile constituents of the oil. Eachsettling chamber is provided with a clean out pipe N, connected with itsrear wall and near the bottom. As the mixture of oil spray and airdischarged from the atomizer flows backward and forward they finallyreach the upper compartment of each retort. From this com artment thehas been produced, ows through a pipe 0 upward into the stabilizer R.

Clean out pipes P are secured to the retorts in line with severalhorizontal partitions therein, and easily removable caps 32 are securedover the ends of these cleanout pipes. There are three stabilizers R, Rand R Each is a metal compartment which extends crosswise of thestabilizer chamber D, and has end brackets which rest on metal beams aset into the side walls of the furnace. Each retort discharges its gasthrough a pipe 0 into the stabilizer R. The V two outside stabilizers R,R engage with asbestos plates which project into the stabilizing chamberfrom the side walls of the furnace. The gas formed in the variousretorts is delivered through numerous pipes 0 into the rear stabilizerR. It passes from this rear stabilizer through a pipe 7' located nearthe middle thereof into the middle stabilizer R; and it passes from themiddle stabilizer R through two pipes r, 7" located near the ends.thereof; and is delivered into the front stabilizer R and from thisstabilizer it is drawn off through the centrally placed pipe 9' \Vithinthe stabilizer chamber and directly over the stabilizers is a battleplate T made of asbestos or other refractory material which is suspendedby bolts i from the furnace dome.

In operation the combustion of gaseous or other suitable fuel in theburner F produces the necessary heat to operate the vaporizing retorts Eabove the burner, the heat and products of combustion passing up throughthe sinuous and gradually diminishing lines or passages K between theretorts, then over and around the stabilizing chambers R above theretorts, thence out through the chimney at the top of the furnace hood.This heat maintains the retorts and the stabilizers at a propertemperature to decompose or vaporize suitable mixtures of oil and airsprayed into them at their lower ends by atomizing injectors Q, whichare pipes connected to any suitable source or sources of supply. Theretorts are preferably charged at their lowest points, which beingnearest the burner F, are the hottest, and consequently the mosteffective in the initial stages of volatilizing the heavy spray-mixture,expanding it and reducing its specific gravity so that its own buoyancyassisted, perhaps, by pressure,incidentally generated in the closedretorts will cause it to rise up through and out of the retorts, andthence through pipes O to the stabilizers above, which receive theproducts of the several individual retorts and mix them to uniform ity.The tortuous shapes of the retort side walls add to their heatingsurface area, While the tortuous flues between them which are contractedin width as they extend upwardly act tocheck the too rapid passage ofthe heat from the burner and give it more time for effective attack onthe retort walls. In addition to having. tortuous side walls theretort-s are provided with series of internal baffle plates which extendalternately from'one end wall nearly to the other, thereby greatlylengthening the retort passage and causing the gases to traverse backand forth the length of the retorts many times before passing out to thestabilizers. The increasing width from bottom to top of the retorts notonly narrows the outside heat fines but, also enlarges their owninternal above that a stabilizing chamber,.a

passages thereby affording space for the increasing attenuation andexpansion of the gases in process of manufacture.

' This apparatus has very great producing capacity in proportion to thesmall space it occupies.

Having described my invention, I claim: 1. In a gas producer, thecombination of a plurality of retorts fixed side by side within thefurnace wall, each retort having sinuous sides which gradually approacheach other from the top downward, thereby forming between adjacentretorts sinuous. flues of decreasing width from bottom to top, andstrips of heat resisting material packed between these retorts near andaround the ends thereof and forming the ends of said fines,
